Blue Hour palette
Wisteria Lagoon
Five stops tuned to sit together without fighting — #0066a6 ink anchors the set, #aed8ff opens it up, and #3891d7, #57adf5, #76bdfb cross the middle in a complementary arrangement. Wisteria Lagoon suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
